All-microwave manipulation of superconducting qubits with a fixed-frequency transmon coupler
Shotaro Shirai, Yuta Okubo, Kohei Matsuura +3
All-microwave control of fixed-frequency superconducting quantum computing circuits is advantageous for minimizing the noise channels and wiring costs. Here we introduce a swap int…
Proposal of an eavesdropping experiment for BB84 QKD protocol with 1-3 phase-covariant quantum cloner
Yuta Okubo, Francesco Buscemi, Akihisa Tomita
We propose an eavesdropping experiment with linear optical 1-3 phase-covariant quantum cloner. In this paper, we have designed an optical circuit of the cloner and shown how the ea…
Experimental demonstration of quantum leader election in linear optics
Yuta Okubo, Xiang-Bin Wang, Yun-Kun Jiang +2
Linear optics is a promising candidate to enable the construction of quantum computers. A number of quantum protocols gates based on linear optics have been demonstrated. However,…
